Individuals – who must make estimated tax payments. If you did not pay your last installment of estimated tax by January 17, you may choose (but are not required) to file your income tax return (Form 1040 or Form 1040-SR) for 2022 by January 31. Filing your return and paying all tax due by January 31, 2023, prevents any penalty for late payment of the last installment. If you cannot file and pay your tax by January 31, file and pay your tax by April 18.
